White Bread
White breads and pastas break down quickly into sugar, and in turn lead to inflammation. In a 2010 study, researchers found that a diet high inrefined grains led to a greater concentration of a certain inflammation marker in the blood, while a diet high in whole grains resulted in a lower concentration of two different inflammation markers.
Alcohol
Alcohol is naturally irritating to our insides, but shouldn’t cause lasting problems unless you overdo it. With a few too many drinks, however, bacteria can more easily pass through the intestinal lining, leading to irritation and inflammation,
Omega-6 Fatty Acids
The average American gets more omega-6 fatty acids via diet than omega-3s, but this imbalance can lead to inflammation, according to U.S. News.
Milk
While moderate intake of low-fat dairy can actually guard against inflammation, whole milk or even two-percent is still high in saturated fat and could mean trouble. But a majority of adults have at least some difficulty digesting milk, so overdoing it could trigger a true inflammatory reaction,
Gluten
Even without a diagnosis of celiac disease, a number of people report feeling better after eliminating gluten from their diet. In fact, a full 30 percent of American adults are now actively avoiding gluten. Science is still largely inconclusive on what’s been called “gluten intolerance,sensitivity that leads to bloating or digestion changes could be an inflammatory response to gluten.
